15.19 5XX Tape Device Rates

Note: Measurements for the high speed devices were completed on a 570 4 way system with 2844 IOPs and 2780 IOA’s and 180 15K RPM RAID5 DASD units. The smaller tape device tests were completed on a 520 2 way with 75 DASD units. The Virtual tape and *SAVF runs were completed on a 570 ML16 with 256GB of memory and 924 DASD units. The goal of each of the tests is to show the capabilities of the device and so a system large enough to achieve the maximum throughput for that device was used.

Customer performance will be dependent on over all systems resources and if those resources match the maximum capabilities of the device. See other sections in this guide about memory, CPU and DASD.
